Title: Projection type display device
Inventor: NOMURA AKIO
IPC: G02B1/11
Filed: 1990-08-18
Abstract: PURPOSE:To prevent the loss of the quantity of light due to reflection and to obtain a bright image on a screen by sticking transparent glass plates coated with reflection preventive films on the incidence-side and projection-side polarizing elements of a liquid crystal light valve. CONSTITUTION:There are the polarizing elements 2 and 3 on the incidence side and projection side of the transmission type liquid light valve 1 which is used as the projection type display device and the transparent glass plates coated with the reflection preventive films are stuck on the incidence-side surfaces of the polarizing elements 2 and 3. Consequently, the loss of the quantity of transmitted light is less than that when only polarizing plates are used and the display image becomes bright. Similar effect is obtained by sticking the reflection preventive glass plates on only one polarizing plates or both the incidence and projection surfaces.

Title: Semiconductor laser element
Inventor: MIYAUCHI NOBUYUKI
IPC: H01S5/16
Filed: 1984-10-16
Abstract: PURPOSE:To enable long time stable high output laser oscillation by setting the mesa width of an exciting region to the injecting width or longer of a current implanting path formed in a strip groove, thereby improving the contribution rate of the implanting current to the laser oscillation. CONSTITUTION:A current for a laser oscillation is blocked by an N type GaAs current blocking layer 32, and the current is implanted only from the implanting portion (current path) of width Wi1, Wi2 at the center and the end of a resonator. The current implanted to the active layer 34 through the mesa having the width Wi1 of the channel groove is formed of a mesa structure having a width Wi1 coupled directly with the mesa in the channel groove or slight wider width than the width Wi1 is the laser operating multilayer crystal, and a high resistance buried layer 36 is contacted directly with the current path of the channel groove. Thus, the leakage current is eliminated to supply to the exciting region of the layer 34.

Title: Transmission type screen
Inventor: MIYAMOTO TAKESHI
IPC: G03B21/62
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To obtain a transmission type screen capable of reflecting a video which is excellent in color reproducibility and is bright and vivid in colors, and having visual recognition in a wide range by incorporating a titanium oxide-coated mica in a transmission type screen and using a synthetic mica as such mica. SOLUTION: This transmission type screen 12 is equipped with a plate-like base material 26, a thin film 28 incorporating a pearl agent using the synthetic mica, and a light diffusion layer 30 both of which are formed on the material 26. The synthetic mica, in which coloring metal is extremely slightly mixed and whose saturation is excellent, is used in the pearl agent to be used. Namely, synthetic mica powder capable of restraining the loss of the light in the process of reflecting and diffusing the light is used in the pearl agent. By using the synthetic mica in which the coloring metal is extremely hardly mixed and whose saturation is excellent, the loss of the light is restrained to the minimum, whereby the luminance of the video on the screen 12 is enhanced, and the transmission type screen 12, on which the vivid video is projected at a wide angle, is realized.

Title: Production of optical fiber coupler
Inventor: WAKINOSONO TOSHIYUKI
IPC: G02B6/287
Filed: 1993-08-09
Abstract: PURPOSE:To provide a production method for optical fiber coupler which determines the characteristic by the tension given at the time of fixing an optical fiber coupler to a reinforcing member. CONSTITUTION:When a tension is given to the optical fiber coupler already subjected to welding and stretching, the characteristic is different by the strength of this tension. The figure shows a modeled emission power/tension curve in one emission port. In an area B1, the emission power is monotonously increased according as the tension is increased. An area A is a maximum area. In an area B2, the emission power is monotonously decreased according as the tension is increased. An area C is the convergence area where the emission power is less varied by the change of the tension. Consequently, the tension corresponding to a desired characteristic is given and the optical fiber coupler is fixed to the reinforcing member in this state.

IPC: G02F1/1337
Filed: 1994-09-13
Abstract: PURPOSE:To increase the yield of element by measuring the difference of absorbance between two orthogonal linear polarized infrared rays reflected on the surface of an orientation membrane thereby measuring the orientative ability of a liquid crystal orientation membrane at high sensitivity and accuracy. CONSTITUTION:An infrared ray R emitted from an infrared light source 1 passes through a Michelson interferometer 3 in a Fourier transform infrared spectrometer and then subjected to polarizing modulation by means of a polarizer 5 and a photoelastic modulator 7. The infrared ray R is deflected by a reflection measuring unit 9 to impinge on an orientation membrane substrate at a specific incident angle and in a specific direction with respect to the orientational direction of orientation membrane molecules and reflected to enter into an infrared photodetector 11. The detector 11 is connected with a lock-in amplifier 13 which is controlled synchronously with the modulator 7 by means of a controller 15. Consequently, switching is made quickly between two linear polarizations and the orientation ability of liquid crystal is evaluated based on the difference of absorbance (difference between two infrared colors) between reflected infrared rays determined at a processing section 17.

Abstract: PURPOSE:To provide an illumination device capable of making parts common and reducing a cost. CONSTITUTION:Light is guided to the entire surface of a light transmission plate 1 from an illumination section 2 and irradiates the light transmission plate 1 from its side faces when a fluorescent lamp 3 is lighted. The light diffuses at a relatively small quantity near the illumination section 2 at a light diffusion surface 4. The diffusion quantity is increased toward the parts increasingly distant from the illumination section 2 and nearly uniform brightness is attained over the entire part of a transparent film 6. The direction of a pictogram is set in an arbitrary direction with the transparent film 6 faced front or rear in order to match the direction of the pictogram with, for example, the direction of an emergency exit, etc., at the time of mounting the transparent film 6 on a light exit surface 5. Since the transparent film 6 is usable at the front and rear, correspondence with one sheet of the transparent film 6 is possible without using two sheets of the transparent films displaying the different directions.

Filed: 1987-09-02
Abstract: PURPOSE:To reduce the size of adding portion of winding and to prevent removing and projecting of terminal, by employing stepped terminals of rods then facing short terminals each other and holding them between long terminals. CONSTITUTION:Terminals 1a, 2a and 1a', 2a', of two lines of spiral rods 1, 2 in tight contact with each other are shifted each other, where long terminals 1a, 1a' and short terminals 2a, 2a' are coupled in step. In other word, short terminals 2a, 2a' face each other at the inside and held between the long terminals 1a, 1a'. Since substantially three lines of spiral rods are arranged in parallel at a joint, the size of the joint is reduced, and defect in electrical characteristic due to concentrated potential gradient caused by unarranged outside terminal can be eliminated. Furthermore, since the joint is constituted with similar single members, the outside terminal is not removed easily.
